A simple and effective one-pot synthesis of substituted indolo[1,2-a]quinolines has been developed. The desired products were obtained in up to 98% yield when substituted 2-methyindoles were treated with 2-iodobenzaldehyde in the presence of Cs2CO3, CuI and l-proline. Our mechanistic study confirmed that the reaction sequence involved an intermolecular Knoevenagel reaction followed by an intramolecular
已开发出一种简单有效的取代吲哚[1,2- a ] 喹啉的一锅法合成方法。当在Cs 2 CO 3、CuI和l-脯氨酸存在下用2-碘苯甲醛处理取代的2-亚甲基吲哚时,以高达98%的产率获得所需产物。我们的机理研究证实,反应序列涉及分子间 Knoevenagel 反应,然后是分子内 Ullmann 型偶联反应。此外,发现一些合成的化合物对人乳腺癌 (MCF-7) 和结肠直肠 (HCT-116) 癌细胞具有活性,IC 50值分别为 27.96 μM 和 6.21–46.91 μM。
